Embodiment 1

[0017] A method for preparing a flexible display matrix material is as follows:

[0018] 1. Preparation of acetylated nanofibril cellulose into film:

[0019] Take about 0.3g of acetylated nanofibrillar cellulose with a dry weight of about 0.02% and dilute it to 150mL of a suspension with a concentration of 0.02%. After stirring for 2 hours, use a hydrophilic polymer with a diameter of 90mm and a pore size of 10-15μm. The G2 sand core funnel of the tetrafluoroethylene organic filter membrane was used for vacuum filtration to prepare the acetylated nanofibrillar cellulose membrane. Take out the filter membrane together, cover an organic filter membrane on the acetylated nanofibril cellulose membrane, and cover the filter paper on the organic filter membrane, then clamp the sample with two glass plates and apply a pressure of 30N, place Dry at room temperature for 12 hours, and then move to a drying oven at 55° C. for 24 hours to finally obtain a dry, flat and smooth acetylated...

Abstract

The invention discloses a preparation method of a flexible display substrate material. The method comprises the three steps as follows: 1) preparing a membrane from acetylation nanofibrillar cellulose; 2) impregnating the membrane in acrylic resin under negative pressure; 3) curing a composite under ultraviolet light to complete preparation of the flexible display substrate material. The preparation method has the advantages that the preparation method of the flexible display substrate material is environment-friendly, and the flexible display substrate material is endowed with better light transmittance, thermal properties, flexibility and surface flatness.

Description

technical field [0001] The invention belongs to the field of nanofibril cellulose composite materials, in particular to a method for preparing a flexible display matrix material. Background technique [0002] The composite of nanofibril cellulose and polymer material can make the material obtain more excellent performance. According to the structure, performance and application requirements of polymer materials, nanofibrillar cellulose can be used as a reinforcing phase in the preparation of nanocomposites to improve the strength of composites and reduce production costs, while developing environmentally friendly and efficient of different materials. Therefore, nanofibrillar cellulose can provide a new type of nanocomposite matrix for flexible screens, solar cells, flexible electrode materials, and conductive paper. [0003] Optoelectronics technology and flexible electronic materials have grown rapidly in the past decade. In the field of electronic displays, flexible scre...
